Software engineer building AI tooling and ad tech at Zynga.

General notes

  1. 1.

    I'm a software engineer on Zynga's AdTech team in Toronto. I designed and led our internal tooling for ad-serving configurations, an MCP (Model Context Protocol) server and tools that let AI assistants work with ad-serving configuration, and a project that helps our games identify high-value ads. I also worked on an AI LiveOps agent that cut a 2–3 hour workflow to about 20 minutes.

  2. 2.

    Outside work, I automate things I'd rather not do by hand. My longest-running side project started in 2023 as a Playwright script that booked my parents' tennis courts the moment booking opened; it's now a TypeScript monorepo with a web app, an API and a bot that runs every morning on a Raspberry Pi. Right now I'm building a platform for delegating software work to coding agents, where results have to be verified independently instead of taken on the agent's word.

  3. 3.

    I studied Software Engineering (Co-op) at McMaster University. Along the way I interned at Hexagon Manufacturing Intelligence, Exchange Solutions and InsideDesk, was a teaching assistant for two engineering courses, and built projects at DeltaHacks, MacHacks and MEC.

Projects

  1. 1D-301

    Detail 1 · Tool · 2026

    Agent Platform

    Agent Platform · screen · scale NTS

    A control plane for safely delegating software work to autonomous coding agents.

    A harness-agnostic platform for handing software work to coding agents in Cursor, Claude Code or any other harness. The goal, from my spec: maximize architecture-approved, verified engineering output per dollar and per minute of human attention.

    Role Solo: spec, design and CLI (in progress)

    1. Wrote the v3 spec: missions, workflow templates, task and role contracts, review gates, model routing, memory and fleet security.
    2. Built the “agent” control-plane CLI in TypeScript: it scaffolds a target repo, validates artifacts against JSON Schemas and runs the claim → start → submit → gate loop.
    3. Workers never certify their own work: a task passes only with an evidence bundle, independent verification, and spec, quality and architecture review.
    4. Routes each task by risk to a capability tier (frontier, strong, mid, cheap), mapped to models by policy instead of hard-coded vendors.

    TennisBooker

    TennisBooker · screen · scale NTS

    Books tennis and pickleball courts the moment booking opens, every morning.

    My parents had to set a 7:30 a.m. alarm every week to get courts at our local club, so I automated it. Members set weekly schedules in a web app, and a bot books the courts each morning and texts the results.

    Role Solo, full-stack (2023 version with help from Douglas Chen)

    1. The bot logs in at 7:25, builds every reservation, then fires at exactly 7:30 a.m. ET for courts 7 days out, falls back to backup courts and texts results via Twilio.
    2. TypeScript monorepo (Turborepo): Express + Prisma/PostgreSQL API with Auth0 roles and machine-to-machine tokens for the bot, and a React, MUI and TanStack Query web app.
    3. Runs in Docker on a Raspberry Pi: CI builds multi-arch images to GHCR, deploys go staging → smoke test → promote with one-command rollback, and Vitest and Playwright suites cover the code.
    4. Began in 2023 as “Alfred”: a Playwright bot on a cron-scheduled GitLab pipeline, with a React and Express app, Firebase and multi-user Auth0 login, used by 2 clients. In Aug 2026 the bot moved to the booking platform’s new GraphQL API.

    PlatefulAI

    PlatefulAI · mobile view · scale NTS

    Mobile meal planner: pick meals, get a grocery list, track calories and protein.

    A mobile-first meal planner: choose meals and servings, turn them into a grocery list, and track calories and protein against personal targets. Our team of five built it as a front-end prototype on mock meal data, so the “AI-powered meal prep” step is a UI concept.

    Role Team of 5: app shell, Auth0 login, meal-planning flow, deploy

    1. Set up the React + Vite app with Auth0 login, the start and home screens and bottom-tab navigation, and deployed it on Vercel.
    2. Built the meal-planning flow: favourites, filtering out meals that clash with saved allergies and diets, a meal-details view, and meal and serving selection.
    3. Teammates built the grocery list and meal data (Mohammad Mohsin Khan), the calorie and protein tracker (Wajdan Faheem), and profile and target settings (Jasmine Sun-Hu).

    StudySpot

    StudySpot · mobile view · scale NTS

    Find a place to study at McMaster: search, filters, ratings, favourites and a map.

    A mobile-first prototype for finding study spots on McMaster’s campus: search and filter spots, save favourites, mark places visited, rate them, and see them on a map around you.

    Role Solo, front-end

    1. Leaflet map centred on the user’s location (falling back to Thode Library), with a marker and rating for each spot.
    2. Text search, attribute filters, and spot pages where you can favourite a spot, mark it visited and leave a rating.
    3. Runs entirely in the browser: accounts, favourites and visits persist in localStorage. Deployed on Vercel.

    UnPassword

    UnPassword · screen · scale NTS

    A password manager built in one day for the MEC 2024 programming challenge.

    A password manager with Auth0 sign-in, an Express API, and passwords encrypted before they are stored in Firebase. I built it in one day with Willie Pai and Mohammad Mohsin Khan for the MEC 2024 programming challenge.

    Role Team: Auth0 login, JWT-secured API, dashboard-to-API wiring

    1. Added Auth0 login and logout, plus a client service layer that attaches the user’s access token to every API call.
    2. Added JWT verification to the Express API and set up its Vercel deployment.
    3. Connected the dashboard to the API for listing, adding and deleting passwords, with password-strength rules on new entries.
    4. Merged 13 of the team’s pull requests during the event.

    API Resume

    API Resume · screen · scale NTS

    My resume as a REST API: Postman-only, rate-limited, with a joke for anyone who POSTs.

    An Express + MongoDB API that serves my resume as JSON, one section at a time or all at once. Inspired by Eric Lake’s API resume.

    Role Solo

    1. Endpoints for experience, projects, education and contact, a combined /api/resume, and a menu at /api.
    2. Only answers Postman (other clients get a 403), rate-limits each IP per day (429), and meets any non-GET request with a joke 500.
    3. Express and Mongoose on MongoDB, deployed to Vercel with Vercel Analytics.

    CarpoolX

    CarpoolX · mobile view · scale NTS

    Android app that matches riders headed the same way so they can share a taxi.

    CarpoolX matches riders heading to the same destination so they can share a taxi and split the fare, with an upfront fare estimate and safety checks for riding with strangers. Four of us built it as a React Native Android app on a Flask and Firebase backend.

    Role Team of 4: repo lead, most of the Flask backend and auth, core screens

    1. Led the repo: scaffold, navigation and a feature-branch workflow. Merged all 38 pull requests that landed and wrote 119 of 156 commits.
    2. Wrote most of the MVC Flask backend: multi-user Firebase Auth sign-in, tokens kept in the Android Keystore, token-checked endpoints, and the controller and model layers.
    3. Built login and registration, the profile, taxi verification by door code, taxi details and passenger reports.
    4. Teammates built ride requests and matching with Google Maps routes and fare estimates (Henushan Bala), end-of-ride ratings (Rafeed Iqbal) and private group rides (Allison Cook).

    Rest Day · screen · scale NTS

    A workout planner that schedules rest days, not just workouts. Built at DeltaHacks 8.

    A weekly workout planner that deliberately schedules rest days, designed to use Fitbit sleep and activity data to decide when to train and when to recover. Willie Pai and I built it in 36 hours at DeltaHacks 8.

    Role Team of 2: Fitbit API integration, landing page, deploy

    1. Wrote the Fitbit Web API client, which pulls 7-day sleep and activity logs and heart-rate data (a standalone Node script, not yet wired into the UI).
    2. Built the navigation bar and landing page with styled-components, plus the routes for the other pages.
    3. Merged the feature branches, deployed the React app to GitHub Pages, and wrote the README and Devpost story.
